Yep. React was adopted a long time ago and it is also now the "industry winner", so no complaining there. Styletron is also older - created more than two years ago.

However, CSS in JS is more controversial and there are some other more popular libraries now. We keep monitoring them and at the same time we are bringing the best features back into Styletron. Also, you could use BaseWeb+Styletron and some other CSS solution for everything else. It's not a big deal (Styletron has like 7kB). But all CSS in JS libs are very similar anyway.

So overall, Base Web was not a big tech switch, React and Styletron have been already widely used.
